Midwinter flowers

Yes, I know that in the United States the winter solstice is considered the first day of winter, but you can’t convince me that the shortest, darkest day of the year isn’t midwinter. My garden, which today sat under low grey clouds, is at its lowest ebb, but in my greenhouse there are at least a few flowers to brighten the gloom. Here are three:

Paphiopedilum gratrixianum

P. gratrixianum is one of the plain-leaf slipper orchid species that have glossy, rather elegant flowers, one per inflorescence. It is closely related to P. villosum (Photo 6 here) which is also flowering this week.

Sinningia bullata

S. bullata was described in 2010 from material collected in Santa Catarina, Brazil, surprisingly recent for such a striking plant. Its species name refers to the bullate (blistered) foliage, but the bright flowers are what draw the eye at this time of year. Unlike many Sinningia species which require a dry winter dormancy, S. bullata seems to grow year-round. New stems sprout from the tuber almost immediately after the old ones die back, and even when not in flower the plant is attractive for its neat foliage with an attractive texture up top and soft woolly indumentum underneath.

Columnea microcalyx (syn. C. gloriosa)

Like S. bullata, C. microcalyx is a member of the Gesneriaceae, the african violet family. This species is an epiphyte from Central America, and its long, trailing stems are best managed in a hanging basket. My plant, started from a cutting about 18 months ago, is covered in buds and will probably look spectacular in about 4-6 weeks, but I couldn’t resist taking a picture of one of the first flowers to open. This species is usually labeled C. gloriosa in cultivation, but Kew considers that name to be a later synonym.
